Alternative Approaches for Waterhammer Analysis and Pipeline Protection
This paper provides a brief review of typical waterhammer problems and their solutions for pumping systems. Alternative approaches to identify and resolve design problems are discussed....
Vertical Transport of Fine-Grained Sediments in Suspensions
Numerical-model sensitivity studies were made to determine the effect of bed flux on the vertical distribution of fine-grained material suspended in turbulent flow. The transport equation...
Numerical Modelling of Pollutant Transport from a Pond to a Stream
The problem of transport of pollutants in groundwater flow from a polluted shallow pond to a natural stream is considered. A numerical model predicting changes in quality of ground water...
Numerical Modeling of Fine Sediment Physical Processes
Fine sediment in channels, rivers, estuaries, and coastal waters undergo several physical processes including flocculation, floc disruption, deposition, bed consolidation, and resuspension....
Prediction of Shoaling in Estuarial Channels: A Microcomputer Application
Shoaling rates at three predominant areas of sedimentation in the Hooghly River estuary, India, have been predicted using a sediment transport model run on an IBM compatible microcomputer....
The Impact of the I-664 Bridge-Tunnel Crossing on Sedimentation
A sedimentation evaluation was made of the proposed I-664 Bridge-Tunnel complex across the James River, Virginia. This paper briefly describes the procedures used and the results obtained...
Tidal Inlet Sand Transport in Rollover Pass, Texas
For Rollover Pass, which is a man-made, artificially stabilized tidal inlet located on the upper Gulf Coast of Texas, the magnitude of the net sand transport through the Pass was estimated...
Data Base Development and Analysis for Water Distribution Systems
There have been a number of studies estimating the costs of repairing, replacing, or renovating aging distribution networks. Although useful in general terms, characterizing a system by...
Levees at St. Louis?More Harm Than Good?
The U. S. Army Corps of Engineers, St. Louis District (SLD), conducted an evaluation into the effects of Federal flood control projects on St. Charles County. Questions to be addressed...
Suspended Sediment Transport from Nonpoint Sources
Precipitation, runoff, and suspended sediment concentration data were collected in a predominantly agricultural watershed in southwestern Illinois from January 1982 through October 1984....
Computer-Based Design of River Bank Protection
A study using the FLUVIAL-11 computer model was made for the Rillito River in order to determine the design configuration for the bank protection which must contain the design flood and...
SEDIMOT II Application to a Large Coastal Watershed
SEDIMOT II was applied to Barker Reservoir watershed in Houston, Texas, in order to simulate sedimentation in the drainage area and the relative effectiveness of sediment control strategies....
The Microcomputer as an Intelligent Workstation in Large Scale Hydrologic Modeling
In an effort to improve the efficiency of the hydrologic modeling activities of the Maryland State Highway Administration (MSHA), a cooperative project between MSHA, the Federal Highway...
Effect of Tall Vegetation on Erosion and Sedimentation: A Microcomputer Package
A model was developed to predict the effect of standing vegetation on sediment yield. The model is based on the relationship between local scour around standing vegetation and the role...
Modeling Unsteady Flows in Large Basins: The Santa Cruz Experience
A case study modeling unsteady flows in a 3,500-square mile basin in the semiarid Southwest has been performed. The evaluation uses novel techniques of mathematical modeling in a data-intensive...
Numerical Modelling of Bed Evolution in Braided Channel Systems
The overall modelling approach adopted is based on an assumption of quasi-steady flow. The numerical algorithm is based on a split-operator approach, in which the flow energy equation,...
Long-Term Ecological Research: A National Perspective
Long-Term Ecological Research (LTER) is an undertaking by the National Science Foundation to promote better planning of research projects and the resolution of major ecological questions...
The Role of Hydraulics and Sediment in Large River Ecology
The National Science Foundation has sponsored a project under the long term ecological research (LTER) program which is called the 'Illinois Rivers' LTER project....
Lake Water Level and Sediment Management?Case Studies in Illinois
Estimation of the sedimentation in the lake is based on the soil erosion rates in the watershed, the sediment transport in the stream system, and lake trap efficiency. Erosion rates are...
